Typical applications

The E2639-VOC(C8H10)-LEL detector is intended for monitoring xylene concentrations in environments such as paint shops, printing works, industrial facilities, chemical stores, laboratories, or other workplaces where solvents, coatings and industrial cleaning agents containing xylene are used.

Xylene (C8H10)

Xylene is a volatile organic compound that readily evaporates into the air and can accumulate in enclosed spaces to dangerous concentrations. Although it has a characteristic sweet odour, it cannot be relied upon as a warning sign, because the sense of smell quickly adapts with repeated exposure and stops detecting it. Exposure may lead to headaches, nausea, dizziness, or irritation of the eyes and respiratory tract, and at higher concentrations or with prolonged exposure there is a risk of serious damage to the nervous system, liver and kidneys.

Smart communication – ideal for fire alarm systems

The E2639 detector combines the advantages of an autonomous safety device and an intelligent communication node. It is designed for seamless integration with fire alarm systems (EPS) and offers a wide range of outputs for comprehensive control:

• Autonomy: 3× volt-free SPDT relays for direct control of equipment or safe system shutdown.
• Connectivity: Dual RS485 Modbus RTU interface for real-time digital export of measured data to a higher-level system (BMS).
• Control: 2× 4–20 mA analogue outputs intended for precise control of the ventilation frequency inverter.

WiFi calibration from any smart device

Compared to the standard version, the E2639-WF has an integrated WiFi module that turns calibration and configuration into a matter of minutes – with no tools and without removing the cover. The access point is activated using a magnetic key, and the configuration interface opens in the browser of a phone or tablet, with no need to download any app. The interface is password-protected with separate access levels for end users and integrators, so everyone works only within their own section of the settings.
